Working with Zacki ELAPOR®
Zacki ELAPOR® has been developed specifically for glued joints in our models which consist of moulded ELAPOR®
foam parts.
Please observe the following points in order to obtain perfect joints:
• Avoid the use of activator. 'Kicker' significantly weakens the joint. We advise leaving joined parts for 24 hours to obtain
maximum strength, particularly when the glued area is large.
• Activator should only be used for temporary, small-area joints ('tacking'). Spray a little activator on one surface, and
allow it to air-dry for about thirty seconds.
• To obtain maximum joint strength you should lightly sand the surface with 320-grit abrasive paper before applying glue.
Bent parts - actually don't exist. If you find that a component has taken up a curve, perhaps after being trans-
ported, it is easy to straighten again. In this respect ELAPOR® behaves in a similar way to metal: bend the
component back slightly beyond the correct position, and the material will then spring back to its proper shape
when released, and maintain it. There are limits, however - don't overdo it!
Bent parts - really do exist. If you wish to paint your model, apply MPX Primer # 60 2700 to the surfaces, wiping it on
very lightly as if you were cleaning the model. Paint must always be applied thinly and evenly, otherwise the component
will warp. Then you really will have bent parts, and they will also be heavy and perhaps even unusable. We have found
that matt-finish paints produce the best visual effect.

1. Before you start
Check the contents of your kit.
You will find Figs. 1 + 2 and the Parts List helpful here.
Completing the fuselage and tail panels
2. Preparing the control "snakes"
The snake outer sleeves 3/2 are supplied 700 mm long. The
first step is to cut them to the following lengths:
Elevator 43
Rudder 44
Aerial 47
The inner tubes 2/1 are supplied 730 mm long. Shorten the
rudder inner to 705 mm.
Elevator 45
Rudder 46
3. Installing the snake outers in the fuselage shells
Note: we strongly recommend that you glue the snake outer
sleeves 43 and 44, and the aerial sleeve 47, to the fuselage
over their full length, as the sleeves increase the stiffness
of the tail boom substantially.

Ensure that the control systems move freely and smoothly,
and that no glue gets inside the snake outer sleeves.
Left-hand fuselage shell:
Fit the elevator snake 41, 45, 43 (steel rod length: 770 mm)
in the left-hand fuselage shell, with the pre-formed end of
the steel rod at the nose. Fig. 3
Position the snake outer 43 flush with the front part of the
fuselage, as shown in Fig. 4. Lay the shell down flat, and
glue the outer sleeve 43 in the channel over its full length
using cyano. Fig. 5
Right-hand fuselage shell:
Fit the rudder snake 42, 46, 44 (steel rod length: 720 mm)
in the right-hand fuselage shell, with the pre-formed end of
the steel rod at the nose.
Fig. 6
Position the snake outer 44 flush with the front part of the
fuselage, as shown in Fig. 7. Lay the shell down flat, and
glue the outer sleeve 44 in the channel over its full length
using cyano.
